THOMAS STENHOUSE, OF WASHINGTON, PENNSYLVANIA, ASSIGNOR 'IO HAZEIJ-ATLAS t. I" COMPANY, OF WHEELING, WEST VIRGDNTIA.

VIRGINIA, A' CORPORATIOH. OF WEST MECHANISM FOR DELIVERING GLASS.

To all whom it may concern:

Be it known that I, THOMAS STENHOUS-E, a citizen of the United States, and a resident of Washington, Washington county, Pennsylvania, have invented new and useful Improvements in Mechanisms for Delivering Glass, of which the following is a specifica tion, reference beinghad to the accompanying drawings, in which- Figure 1 is a section showing the application of my improved mechanism for delivering glass from a furnace spout; Fig. 2 is a section on lines II.II of Fig. 1; Fig. 3 is a section on lines IH-HI of Fig. 1; Fig. 1- is a'partial front elevation of my device; Fig. 5 is a section on lines VV- of Fig. 4c, and Figs. 6 and 7 are details of one of the containers.

My invention relates to the deliveryv of glass in predetermined quantities from a furnace into suitable receptacles, and consists in mechanism for drawing molten glass into a movable container and in bringing the container when filled with glass into discharge position over a suitable receptacle. My invention also'relates to the construction and arrangement of parts which I shall hereinafter describe and claim.

Referring to the drawings, 2 indicates a furnace spout, which has the usual discharge orifice 3 in the under side thereof, and 4: 1s

a water-cooled bed or plate secured on the under side of the spout and which has an aperture 5 registering with the orifice in the furnace spout. Below the plate 4 is a rotatable disk 6, which has-containers 7, 7' in its periphery, of which I have shown two, each of which is adapted in one position to be brought into registry with the aperture 5 and orifice 3, and also in another position into registry with a receptacle'or mold 8, positioned directly beneath the rotatable member 6. About the lower edge of the aperture 5 is positioned a hardened metal ring or cutting edge 9, against which a corresponding ring 10 in the outer face of each container is ada ted to shear the molten glass. The mova 1e disk 6 has a rearward Specification of Letters Patenta second fluid pressure cylinder 16, which is actuated by a cylinder 17.

When the device is set in operation one of the containers 7 is brought into register with the orifice 3 and aperture 5, and the cylinder 17 is actuated so as to operate the cylinder 16 and draw out the air from such container through the port 18. When the container is filled with glass the cylinder actuates the rack 13 to rotate the member 6. As the member 6 begins to oscillate, the ring 9 cuts off the glass against the ring 10, and after the disk has described a half revolution it is halted with the container 7 in discharge position immediately above the receptacle 8, thus bringing the container 7' in register with the orifice 3 and aperture 5. As the air is then evacuated from the container 7, which is nowin receiving position, the action of the piston in the cyl inder 16 will drive the air through the port 18 into the container 7 first filled, and will thus force the glass down into the receptacle'8.

The operation will thus be continued, and with each movement of the revoluble-member 6 an empty container will be brought into position to receive molten glass, while the other container will be brought into position to discharge glass into a receptacle or mold.

I have shown a recess 19 in the periphery of the rotatable member 6, inclined toward the outer face of the member, which permits the glass to flow from the. orifice 3 and aperture 5 preliminary to starting up the machine, or which may be used in case the operation of the machine has been stopped for a short time. In normal operation the disk 6 describes only a half revolution, and hence the recess 19 in the disk is only brought into register with the aperture 5, as is shown in Fig. 5, when retraction of the adjusting member 20 permits the piston Patented Aug. 6, 1918.

14, and with it the rack 13, to travel farther to the right and rotate the disk beyond its normal position. The containers 7, 7 each have a bottom plate 21 secured therein and arranged to support the glass in the container, and at the same time permit the ingress or egress of air therearound, as is shown in Fig. 6.

My invention is of great advantage, since it enables the production of Ware made from very hot and homogeneous quantities of glass in a very rapid and efficient manner.

The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any mechanical equivalents of the features shown and described, or portions thereof, but recognize that various structural modifications are possible Within the scope of the invention claimed.

What I claim is:

In apparatus for delivering glass from furnaces or the like, a furnace spout having an aperture in the underside thereof, a rotatable disk having on its periphery a plurality of containers for the glass, and a receptacle, each of said containers being adapted to be rotated into position to receive the glass from the aperture and to carry it into position to discharge into the receptacle, said disk having a rearward extension containing fluid pressure mechanism, ports connecting said fluid pressure mecha-' nism with each of said containers, and a plunger operating therein, adapted to evacu
